When flying from somewhere in Europe to the British capital of London, you will likely have many different flight options. However, the airlines that you will be choosing from will likely fall into one of two categories. For starters, the airline might be a full-service network carrier or an airline that offers flights tailored to business travelers and funnels passengers through large hubs. These airlines offer a better passenger experience, and they do not charge passengers for things like seat selection or carry-on bags.
